Techniques are described herein to reduce link flapping scenarios in existing Radio-Aware Routing (RAR) technology, on both the server side and the client side. Existing techniques provide no mechanism to prioritize vendor-based or reliable/preferred clients. In particular, Open Shortest Path First (OSPF) protocol and/or Enhanced Interior Gateway Routing Protocol (EIGRP) often initiate a call based on link quality and other metrics at that moment in time, which may lead to constant link/session flapping. This is due to the limited set of link characteristics relied upon by existing techniques for computing session establishment to a Dynamic Link Exchange Routing (DLEP) client. The techniques described herein introduce added parameters for better convergence to enable prioritization of reliable clients, thereby enhancing existing RAR protocols (e.g., DLEP). Thus, latency and performance with wireless clients may be enhanced in the industrial Internet of Things (IoT) routing space.
